我正在尝试修改URL并将流量重定向到一个没有尾随斜杠的新URL。下面是我当前的服务器块：

server {
        listen              443 ssl;
        server_name         www.example.com;
        ssl_certificate     /path/to/certificate.crt;
        ssl_certificate_key /path/to/private/key.pem;
        ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
        # redirects manually entered here: 
        location /long-url-1/ { return 301 https://example.com/short-url-1; }
        location /long-url-2/ { return 301 https://example.com/short-url-2; }
        # all other traffic should be redirected by the rule below:
        location / { return 301 https://example.com$request_uri; }
}

我想修改以下位置块：

# all other traffic should be redirected by the rule below:
    location / { return 301 https://example.com$request_uri; }

如果用户输入：

https://www.example.com/unknown-url-1/ => (www + with slash) the rule should redirect to:  https://example.com/unknown-url-1 (non-www + no trailing slash)

或者如果用户输入：

https://www.example.com/unknown-url-2 => (www + no slash) the rule should redirect to:  https://example.com/unknown-url-2 (non-www + no trailing slash)

我认为有两种方法：
1.通过实现两个位置块，一个用于带有斜杠的URL请求，一个用于所有没有斜杠的URL，例如：

location / { rewrite ^/(.*)/?$ https://example.com/$1 permanent;}
    location ~* /(.*)/$ { return 301 https://example.com/$1;}

1.通过在我现有的位置块中添加重写并以某种方式修改$request_uri，例如：

location / { 
 rewrite ^/(.*)/$ /$1 break;
 return 301 https://example.com$request_uri; 
}

显然，上述片段不工作，我将感谢您的帮助。
